Add jiff support

[StratusFearMe21]

This PR adds initial jiff support to these bindings. It's a newer date/time library inspired by JavaScript's Temporal API. jiff is unique in that it has a Span type that can accurately perform arithmetic with calendar units like days and moths. Jiff's span type also losslessly converts to and from DuckDB's interval type.

This PR also has some fixes for the implementation of chrono. For instance, the FromSql implementation for chrono::NaiveTime and chrono::NaiveDate used chrono::NaiveDateTime::parse_from_string(), which crashes if the underlying ValueRef is a string, since you need both a date and a time to construct a NaiveDateTime. I've made sure to add more unit tests for the bugs I did find.
